Explanation / Answer

Program :

#include<iomanip.h>
#include<iostream.h>
#include<conio.h>
#include<math.h>
class interest1
{
public:
double amount,length,i,n,p,count,interest;
float installment,r;
public:
void accept()
{
cout<< " Enter loan amount: " ;
cin >> amount ;
cout<< "Enter interest rate (%): ";
cin >> interest ;
cout<< "Enter length of loan (years): ";
cin >> length;
}

void display()
{
cout <<" TABLE OF LOAN PAYMENTS ";
for(count=1;count<=5;count++)
{
cout<<" ";
cout<<amount;
amount=amount+10000;
}
}
void check()
{
for(count=1;count<=length;count++)
{
cout<<" ";
cout<<interest;
n=length*12;
r=interest/1200;
p=amount;
for(i=1;i<=5;i++)
{
installment=(p*r*pow((1+r),n)/(pow((1+r),n)-1));
p+=10000;
cout<<" ";
cout<<installment;
}
interest+=0.25;
}
}
};
void main()
{
clrscr();
class interest1 i;
i.accept();
i.display();
i.check();
getch();
}
